Servos are small boxes that has a DC motor inside and a gear box, it also has a potentiometer that tracks its position and makes them perfect for going to specific angles. But there is a downside, it can't move past 360 degrees so it is useless for using as motors on a car.

So in this project you will learn how to make an continuous rotating servo (never stops), for robotic purposes like putting one on each side of a chassis with wheels

Step 1: Parts & Tools

Here is a list of parts and tools I used for this project.

Parts

The servo that you want to hack.
Two wires.

Parts

soldering iron and tind.
cutting plier.
screwdriver.

Step 2: Removing

Take your screwdriver and screw the screws on the bottom of your servo out. Take away the bottom and the top cover, but be careful when lifting the top cover off, it might be gears falling out.

There is many layers of gears inside, the gear thats on the top you need to take off and do some changes to. you can see on the photo above that there is two small plastic pins sticking out off de gear, you need to cut those off, they are there so the servo wont go any further than 180 degrees.

Next you need to cut the connections to the potentiometer and motor, than remove the circuit board out of the servo.

Drag the rubber gasket off the servo wires, than you can have it on your new vires so the servo doesn't get water damage and the vires will hold better.

Step 3: Soldering

De isolate the two new wires about 0,5cm at the ends and solder them to the motor connections.

Step 4: Finishing

Set all of the gears back together as they were and push the top cover on again.

Slide the rubber bearing on the cable and close the servo up with the bottom cover.

Take the 4 screws and screw them back into the holes.

Now that you are finished than you can connect the servo to your electronics and start rolling.
